In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present application.
Example 1: the application relates to a water and sand flux synchronous on-line monitoring method based on sound and light signal fusion, which is used for carrying out real-time monitoring and fluctuation assessment on the water area state by matching with a sensor on a lead;
the technical conception of the scheme is as follows: considering that the basin has diversity due to environmental and weather influences, constructing observation points in a plurality of areas of the basin, wherein each observation point is provided with a lead, and parameter information is obtained by moving the lead in the area, and is uploaded to a local data end and a remote data end, so that the local data end can record data at shorter time intervals in a normal state, and the remote data end usually records data at longer time intervals due to corresponding to the plurality of local data ends.
When a specific situation occurs, the local data end and the remote data end are recorded simultaneously to ensure the stability of the data. And simultaneously adjusting the working state of the lead, wherein the adjustment can adjust the lead in the area and the lead in other areas related to the area.
When the remote data end and the lead fish are delayed in transmission or the remote data end and the lead fish transmit information, the lead fish is temporarily controlled through the local data end, so that the lead fish can be guaranteed to be quickly corresponding, and then in a delayed state, the remote data end transfers signals from the local data end, and the adaptation adjustment of the lead fish is realized.
When the connection between the remote data end and the local data end is interrupted, the local data end can also control the lead fish and record the data through preset parameters, and after the remote data end is connected with the local data in a recovery mode, the data is uploaded in time, so that the risk of data loss is reduced.
Specific: and determining the working state of each sensor of the lead, and transmitting the lead main control computer with the local data end and the remote data end in a point-to-point manner. The local data end and the remote data end are mainly used for constructing local area network structures of the local monitoring station and the remote central station, namely the local data end is a service end of the local monitoring station, and the remote data end is a service end of the remote central station. And binding the IP address of the local data end by the remote data end to perform point-to-point access, and meeting the corresponding requirement of the control access of the remote metering. The local data end can be provided with a common optical fiber broadband, and the remote data end can be accessed through a fixed IP special line and a VPN central server.
And distributing a plurality of lead fishes in different areas of the river basin, carrying out data acquisition by the lead fishes, and outputting data streams of the water area environment to a local data end and a remote data end. Each lead corresponds to a local data end, and a plurality of local data ends correspond to a remote data end.
When the lead fish works, starting a main control machine of the lead fish to perform hour time counting, and adjusting the lead fish to be in a conventional state; and carrying out data interaction on the local data end and the remote data end. The main control machine of the lead fish counts by using the hour hand through the clock timing, and sets different time nodes, and the lead fish is collected in a time-sharing way on the corresponding time nodes. The collected data flow is transmitted to a local data end or a remote data end through a lead fish main control machine, and data interaction is carried out between the remote data end and the local data end, so that the remote data end can read the data of the local data end in real time to acquire real-time water area state information.
When the lead fish monitors that the fluctuation of the amplitude of the sediment is increased, the warning threshold delta h of the sediment sensor is started, and the lead fish transmits the data stream to the local data end and the remote data end simultaneously, and the local data end synchronously packs and uploads the near-term data to the remote data end.
Wherein Δh is typically a drainage basin warning parameter, typically the parameter of Δh is 80% of the value of the risk parameter; the dangerous parameter value refers to that the sediment amount can cover the sensor on the lead fish, so that the acquired parameters of the sensor are seriously distorted; and may result in the lead not being free to move or to reach the desired monitoring location.
When fluctuation of the amplitude of the sediment is increased, the sediment sensor needs to be compared with deltah every time data are acquired, when the acquired data is close to Δh, a lead shutdown or lead recovery may be required to ensure equipment safety.
Typically the Δh parameter is 80% of the sediment increase actually possible for the fish in the lead operating state. The sediment increment affecting the working state of the lead is usually that the lead may be covered with a sensor in a short time, which causes serious distortion of the sensor acquisition parameters and may cause the lead to not move normally or reach the required monitoring position.
When the lead fish is in a normal state, the sediment sensors of the lead fish respectively acquire data in a time-sharing manner at a first time node and a second time node; the lead fish main control machine outputs sediment data to a local data end at a first time node; and outputting the sediment data to a remote data end by the lead fish main control computer on the second time node.
The first time node is a time loop performed at any one integral point in units of minutes, which means that the sediment sensor performs data acquisition at the minute moment of each integral point, for example, a counting mode of wireless circulation at intervals of every 1 st minute, every 3 rd minute and every 5 th minute. The second time node may be a time loop of any parameter point in units of hours, such as a counting mode of wireless cycle every 0.3 hour, 1 hour and 2 hours. To facilitate certain crossing between the first time node and the second time node, the interval time selected by the second time node may be generally a multiple of the interval selected by the first time node. For example, the first time node is at intervals of every 5 minutes and the second time node is at intervals of every 60 minutes.
Example 2: based on the above embodiment, in another embodiment of the present application, the point-to-point transmission is performed between the master control unit and the local data end through a wireless network, and a standby network cable is provided between the lead and the local data end.
When the remote data terminal generates delay response, the remote data terminal does not influence the acquisition of data in a networking delay state, so that the fluctuation condition of the data stream can be analyzed conveniently.
When the lead fish is required to perform high sensitivity and quick response, the local data terminal can always keep stable information transmission with the lead fish. Meanwhile, the command of the remote data end can be transferred through the local data end in a delay state so as to meet the requirement of adaptively adjusting the lead fish in different areas according to different scientific research requirements.
And secondly, under the condition of network disconnection, corresponding data streams can be obtained as much as possible under various working conditions through a local data end and a spare network cable of the lead fish, so that information loss caused by data loss or transmission interruption is avoided.
Example 3: based on the above embodiment, referring to fig. 1, another embodiment of the present application is that when the lead fish is in a normal state, the sediment sensor sets an amplitude alarm parameter Δc (t) when collecting at the first time node, and correlates the water sediment flux parameter C (t) collected by the sediment sensor at the time and the sediment parameter C (t-1) collected at the previous time with Δc (t).
The ΔC (t) is a parameter value which needs to exceed normal fluctuation, and C (t) -C (t-1) is in the range of ΔC (t), and the sediment amplitude is normal, so that the lead fish main control machine maintains the working states of the first time node and the second time node. When C (t) -C (t-1) exceeds the range of delta C (t), and the sediment amplitude is abnormal, the lead fish main control machine outputs C (t) data to the local data end and the remote data end simultaneously; after the local data terminal receives the C (t) data, the local data terminal transmits the marking parameters to the remote data terminal.
Further, referring to fig. 2, when the remote data end receives the marking parameter, the remote data end sends a first feedback signal and a second feedback signal to the lead and the local data end, respectively, where the first feedback signal includes a control code, and the second feedback signal includes a status code.
When the lead fish receives the first feedback signal, carrying out an updating strategy; by receiving the first feedback signal, the lead can respond accordingly according to the update strategy. The working state of the lead fish can be timely adjusted to adapt to the changing requirements of the basin environment.
And the local data end receives the second feedback signal and corrects the setting parameters of the lead, so that the lead is in the first regulation mode. And detecting the state of the lead fish through the local data end after receiving the second feedback signal, recording working state data of the lead fish by the local data end, and if detecting that the state of the lead fish is abnormal, correcting and adjusting setting parameters of the lead fish by the local data end to enable the lead fish to be in a first regulation mode. Thereby effectively ensuring the efficiency and operability of the change of the working condition of the lead fish.
Wherein the update policy is: the main control machine of the lead fish resets the hour time of the sediment sensor, and the original first time node is covered to be a third time node through the main control machine.
The first regulation mode is: enabling the lead fish to start a warning threshold delta h of the sediment sensor on a third time node; and the lead fish main control machine simultaneously transmits data to the local data end and the remote data end in real time.
Further, in the first regulation mode, in the third time node range, the parameters acquired by the sediment sensor are always smaller than the warning threshold value deltah, and then the lead exits the first regulation mode and resumes the time-sharing data acquisition at the first time node.
The third time node is usually counted down, and the unit is usually hours, for example, the third time node is 5 hours, and the lead fish works according to the first regulation mode within 5 hours after entering the update strategy.
Example 4: based on the above embodiment, referring to fig. 3, in another embodiment of the present application, when the local data terminal sends the marking parameter, the clock of the local data terminal marks the clock node T1 at the same time, and when the local data terminal does not receive the second feedback signal of the remote data terminal within the time range of the clock node T1, the local data terminal makes the lead fish in the second regulation mode by means of the preset parameter.
Second regulation mode: covering the first time node as a preset fourth time node, setting a preset safety parameter delta h (K) of the sediment sensor, acquiring sediment information in real time through the lead fish, determining the difference value between C (t) and delta h (K), and recording through a local data end.
In the second regulation mode, the connection between the remote data end and the local data end is interrupted, and at the moment, the local data end takes the data output by the lead fish as offline data to carry out local storage and intermittently try reconnection of the remote data end.
Since the second regulation mode usually occurs when the local data end and the remote data end are disconnected, Δh (K) is set, which is usually a safety value carried by the basin. The fourth time node performs compartment collection within a reserved time value range, for example, reserved for 10 hours, for example, within 10 hours when the lead fish enters the second regulation mode, needs to collect every 3 minutes, and obtains data as much as possible by keeping high-frequency operation in the second regulation mode. When the local data end and the remote data end are successfully connected, the difference data can be timely fed back to the remote data end. And remotely stopping the second regulation and control mode through the remote data end according to the difference data, and adaptively setting the lead.
Example 5: based on the above embodiment, another embodiment of the present application is that the first time node is a time node for collecting every N minutes, and the second time node is a time node for collecting every N hours, where N is a number between 0 and 24.
The local data end and the remote data end are both used for controlling the lead fish through the main control computer, and the control authority of the remote data end is greater than that of the local data end.
The method is applied to the river basin environment, when the river basin is abnormally changed, the information possibly collected by the lead fish in different areas can be fluctuated differently, and the remote data end is accessed to the local data end, so that after parameters are analyzed, the lead fish in different areas can be adaptively adjusted, and the requirements of observation and scientific research are met. For the area where the lead risk may exist locally, the local data end can be used for rapidly corresponding to the lead and reporting the lead to the remote data end, and the remote data end is adaptively adjusted according to the actual situation.
According to the actual requirement, when the lead fish is required to perform damaging work, the preset operation of the local data end can be regulated or prevented through the authority of the remote data end.
Further, sediment data collected by the lead at the first time node are output to a local data end and form a first parameter set of { C (t), C (t-1) … … C (t-N) } according to a time sequence; the sediment data collected by the lead fish at the second time node is transmitted to a remote data end and forms a second parameter set { P (t), P (t-1), P (t-2) … … P (t-N) } according to a time sequence; the first and second sets of parameters are each used to form a graph.
The data collected by the lead fish in the conventional state is plotted according to time, and the local data end and the remote data end are conveniently subjected to data comparison by using the graph.
For example, the graphs of the local data ends in different areas within a constant time range are uploaded to the remote data end for comparison.
